Rising Temperatures and Surface Mass Loss in Greenland: Implications for Regional Glacier Dynamics and Global Sea Level Rise
Abstract: In Greenland, the ice sheet serves as one of the strongest indicators of global climate change, with consistently rising temperatures driving it toward an even more negative mass balance. Over the last two decades, warmer conditions have exacerbated surface melting, darkened ice, and resulted in feedback stimulating further loss. This study assesses how those temperature trends—particularly during summer peak months—have impacted the stability of Greenland's ice, and then, more importantly, …

Recent Development to Track Contraband using Muon
Abstract: The muon is one of nature’s fundamental particles discovered in 1937 by Carl Anderson. A muon is an elementary subatomic particle similar to electron, but with a mass approximately 207 times greater and, sometimes it is called as a “heavy electron”. Muons are generated naturally when cosmic rays collide with atoms in earth’s upper atmosphere and, then raining down all the times upon the surface of earth. Muons can be …

Comparative Study of Rocuronium Bromide and Succinylcholine Regarding Ease of Intubating Conditions and Hemodynamic Parameters for Rapid Sequence Intubation in Adults
Abstract: Background: Rapid Sequence Intubation (RSI) is an airway management procedure designed to quickly secure the airway while reducing the likelihood of gastric aspiration during anesthesia induction. For many years, Succinylcholine has been regarded as the preferred neuromuscular blocking agent for RSI because it produces muscle relaxation rapidly and has a relatively brief duration of action. However, its adverse effect profile – including hyperkalemia, bradyarrhythmias, malignant hyperthermia, and increased intracranial and …
